Thank you for asking the question.
Before i answer the question, you need to know about the indications and contraindications for undergoing a weight loss surgery.
Obesity along with Diabetes is an indication. There is something called the BMI (Body Mass Index) which determines if you are obese or not.
How do you calculate BMI?
BMI = weight (in kgs) / height2(in meter).
For example. Weight of an individual is 70kgs and the height is 170cm.
BMI would be 70/ 1.702 = 70 / 2.89 = 24.22
BMI = 24.22. The normal BMI range for men is 18 to 24 which in this case is considered normal for the given individual.
For undergoing the surgery, your BMI should be more than 40.
If you have a heart problem.
If you have any psychiatric problem.
If you are unable to adjust to the post-operative lifestyles.
Once you’re convinced that you have to undergo the surgery, then there are different types of surgeries that you can consider for reduction of weight. The surgery that is considered by everyone is Bariatric Surgery.
Bariatric surgery or weight loss surgery is done in individuals who were unsuccessful in reducing weight by diet,medicines and exercise.
Procedure: the size of the stomach is reduced by removing a part of the stomach.
Once the size is reduced, the capacity for consumption of food decreases drastically.
And hence reducing the weight.
There are various types of surgeries that you can consider for reduction of weight. I have mentioned about a few of them below.
Sleeve gastrectomy (gastro-stomach, ectomy-to remove)
In this type, the stomach is reduced to 15% of its original size. This is done by removing part of the stomach, so as to reduce its capacity. The cut edges of the stomach are joined using surgical staples or by sutures. This is NOT a reversible procedure.
Stomach volume is reduced, function is not altered.
This procedure involves the placement of a deflated balloon within the stomach, and is inflated to decrease the stomach capacity. This balloon can be left in the stomach for 6 months and has to changed thereafter regularly. This procedure has been approved by many countries including India. The intragastric balloon can also be used before opting the above mentioned procedure to help in weight reduction before the surgery.
Plication means to make folds or pleats.
In this method the stomach is folded on itself and sutured rather than removing a part of the stomach. This helps in preserving the natural functioning of the stomach. It was done in 66 individuals (44 females), they showed significant results in weight loss and no major complications.
Depending on the surgeries, the cost varies.
EFFECTIVENESS OF THE SURGERIES:
Weight loss occurs within the first 10 months after surgery. Upto 50 kg loss has been seen in very obese individuals.
POSTOPERATIVE LIFESTYLE CHANGES
You will not be able to eat much.
One person who underwent this surgery, his daily meal was only one apple, for the full day.
This is because of the reduced size of the stomach.
Most common complication is diarrhoea and bloating of the abdomen.
I hope you got the answer you were looking for.
